1 Claim. 1

The present invention relates to pins or clasps such as are useful asbarrette pins and the like.

The object of the present invention is to provide an all-plastic pinwhich can be inexpensively manufactured and which is capable of beingsecurely clasped.

With this object in view, the present invention comprises the pin orclasp hereinafter described and particularly defined in the claim.

In the accompanying drawings, Fig. 1 is a plan view of the pin; Fig. 2is a sectional elevation; and Fig. 3 is a detail view of the tonguemember.

The pin comprises a base member 4 and a tongue member 6, both preferablymade entirely of molded plastic.

The base 4 has a hook 8 on one end to engage the end of the tongue, anda hinge portion, indicated at Ill, at the other end. The hinge portioncomprises two separated side walls l2, into which a lateral slot l4extends upwardly through the base. The space between the walls I2 ispartly filled above the top of the base, to form a front wall indicatedat l6 of considerably less height than the side walls l2, for a purposeto be explained later.

The tongue 6, as shown in Fig. 3, is flared outwardly from its pointtoward the rear, where it is reduced in width to form a retainingportion I8 of the proper size to lie between the side walls 12 of thebase member. At the extreme rear of the tongue member, there is provideda rodshaped portion 20, serving as a pivot. The entire tongue member isthus generally T-shaped.

The tongue portion is assembled in the base portion by simply pushingthe tongue upwardly through the slot I4. The flared portion of thetongue spreads the walls [2 until the portion l8 snaps into placebetween the walls. Thereafter, the tongue member is free to pivot on therod portion 20.

The front wall l6 between the walls I2 is sumciently high so that theend of the tongue cannot be snapped into the hook without applying asubstantial bending stress to the tongue member. The tongue may be bentslightly sidewise and downwardly to enter into the hook, after which theresilience of the tongue under the pressure of the portion l6 causes theend to engage firmly under the hook.

The pin described above may be cemented or otherwise applied to abarrette or other ornament, indicated in dot and dash lines at 22 inFig. 1.

Having thus described my invention, I claim:

A pin or clasp comprising a base of plastic material having atongue-engaging hook and a hinge portion, the hinge portion comprisingtwo separated side walls, said base having a slot which extends acrosssaid base and upwardly into the side walls, a front wall extendingupwardly from the base between the two side walls, and a T-shaped tonguemember having a rod-shaped pivot portion insertable through said slot, aflaring tongue, and a portion of reduced size adjacent the rod-shapedportion, the rear portion of the tongue being wider than the spacebetween the side walls, the reduced portion of the tongue member beingdisposed between the side walls and engaging the front wall to stressthe tongue to hold it in engagement with the hook.
